ELEVATOR INSTALLATION WITH A SAFETY DEVICE - An elevator system has at least two elevator cars, each of which has at least one elevator car door and each of which is provided for independent displacement in a common shaft, and a plurality of shaft doors and a safety device having at least one door opening sensor, at least one evaluation unit and at least one data line between the door opening sensor and the evaluation unit. The evaluation unit evaluates at least one signal of the door opening sensor in at least one evaluation step to prevent unauthorized opening of the shaft door.

ELEVATOR WITH A MONITORING SYSTEM - An elevator has a control unit, a bus, a first microprocessor and at least a second microprocessor, which microprocessors are associated with a bus junction and which are connected by the bus with the control unit. The control unit communicates an instruction by the bus to the second microprocessor to interrupt a signal transmission to the first microprocessor so that the first microprocessor transmits a status message to the control unit.

ACTUATING AND RESETTING A SAFETY GEAR - A device can actuate and reset a safety gear in an elevator system. The device contains a pressure accumulator, possibly a compression spring, which, in case of need, can move at least two engagement elements of the safety gear essentially synchronously into an engaged position, and a remotely actuatable resetting device, which can retension the pressure accumulator into a ready position.

MONITORING METHOD FOR AN ELEVATOR INSTALLATION - The monitoring method for an elevator installation includes a control unit and at least one bus junction, which bus junction has a receiver, a transmitter and a safety element. The control unit and the bus junction communicate by way of a bus. The monitoring method has the following steps: a digital default signal is transmitted by the control unit to the receiver; the digital default signal is converted by the receiver into an analog signal; the safety element is acted on by the receiver with the analog signal; if the safety element is closed the analog signal is detected by the transmitter; for a detected analog signal, a digital signal of the control unit is provided by the transmitter; wherein on detection of an analog zero signal a digital signal is transmitted by the transmitter to the control unit.

SHAFT ACCESS ENABLING DEVICE OF AN ELEVATOR SYSTEM - A shaft access enabling device of an elevator system has a shaft access control unit and at least one access monitoring unit, wherein the shaft access control unit controls an operating state of the at least one access monitoring unit and the access monitoring unit monitors at least one shaft access. The shaft access control unit has at least two different operating modes for controlling the operating state of the at least one access monitoring unit and inspects access authorization before changing between the at least two operating modes thereof.

FUNCTIONAL MONITORING OF A SAFETY ELEMENT - A method of checking the functional capability of at least one safety element of a safety circuit of an elevator installation utilizes a first processing unit and a second processing unit for the at least one safety element. The at least one safety element is connected with a control unit by a communications network. At least one signal is provided by the first processing unit on the basis of at least one communication from the control unit. The at least one provided signal is detected by the second processing unit connected with the first processing unit and is communicated to the control unit by way of the communications network. The at least one communicated signal is checked for the validity thereof by the control unit.

SAFETY DEVICE FOR AN ELEVATOR WITH A PLURALITY OF CAGES - An elevator has a first and a second cage, which are movable along a common travel path. In addition, the elevator includes a safety device, by which the two cages can be monitored, and a shaft information system, which is connected with the safety device and by which the speed and the position of the two cages can be determined. If the two cages fall below a safety spacing, a first braking measure can be initiated for at least a first cage by means of the safety device. A retardation plot for the at least first cage is predeterminable by the safety device on initiation of the first braking measure. In that case, a second braking measure can be initiated for the at least first cage by means of the safety device if the retardation plot is exceeded.
